A novel, compact, and green method was developed for the determination speciation analysis of mercury, based on flow injection photochemical vapor generation (PVG) coupled with miniaturized solution cathode glow discharge-atomic emission spectroscopy (SCGD-AES). The SCGD generated between a miniature hollow titanium tube emerging from glass capillary. Cold mercury (Hg(0)) by PVG subsequently delivered to excitation, finally signals were recorded spectrograph. detection limits (DLs) Hg(II)...
Trace impurities of sodium, lithium, magnesium, and potassium in colloidal silica were determined by slurry introduction into an atmospheric-pressure solution-cathode glow discharge (SCGD). The applied voltage, solution flow rate, distance between the metal anode surface optimized. Emission from K (766.5 nm), Na (589.0 Mg (285.2 nm) Li (670.8 demonstrated a linear range nearly 4 orders magnitude (R2 ≥ 0.998) steady-state sample yielded limits detection 0.7, 0.4, 0.5 0.2 ng mL−1,...
In this study, miniaturized optical emission spectrometry (OES) based on solution cathode glow discharge (SCGD) was developed for the determination of metal elements in samples.
The quantitative measurement of trace elements in TiO<sub>2</sub>powders using a modified solution-cathode glow discharge-atomic emission spectrometry system has been developed.
We herein report the development of a compact and robust optical emission spectrometry (OES)-based technique for ultrasensitive determination Se As utilizing hydride generation (HG) as sampling direct-current atmospheric pressure glow discharge in He (APGD) radiation source. The sensitivities 50 ng mL–1 newly designed HG-APGD were enhanced more than 3-fold by constraining spatial volume between two hollow-tube APGD electrodes, stability was significantly improved. developed achieved...
We herein describe a novel method of hydride generation (HG) coupled to newly designed atmospheric pressure solution-cathode glow discharge (SCGD) spectrometric technique for the ultratrace determination tin, germanium, and selenium. In this SCGD process, gas introduction was permitted using hollow titanium tube as both anode sampling port. these experiments, analytes were converted into volatile hydrides upon passing through generator, introduced near-anode region system, where they...
The addition of CNTs leads to the formation covalent bonds, defects, lattice distortion and phonon energy localization. introduction reduces IP-TC elastic modulus graphene films, while it increases OP-TC.
A simple, low cost, and accurate speciation analysis method based on on-line SPE SCGD-AES was developed for the determination of hexavalent chromium in aqueous samples.
In this paper, the first demonstration of direct ultratrace determination lead in a single human hair by current-atmospheric pressure glow discharge-atomic emission spectrometry (DC-APGD-AES) coupled with electromagnetic heating vaporization (EMV) was described. Only ultramicro mass sample (about 0.15 mg, often hair) required during analysis, and fast detection implemented without tedious pretreatment processes, such as grinding digestion. A limit (LOD) 30.8 μg kg-1 (4.8 pg) for Pb obtained...
